Strengthening students’ skills in system programming with C by specifically doing process creation and management. Description This is an individual homework. The provided skeleton code implements the parsing phase in the development of a basic Linux shell. The user entry is a number of commands with their arguments, if any, separated by pipes, if any. In the parsing phase the program is already coded to do the following:

1. Infinite loop

1.1. displays a prompt

1.2. reads user’s commands on a line 1.3. check few things,

1.3.1. if the user entry is spaces or empty line, then perform next iteration of the loop i.e., continue 1.3.2. if the user entry is a special command, exit, then exit the loop i.e., break

1.4. performs a tokenization i.e., recognize the commands and store them in an array of a given formatted structure.

1.5. calls a function print_commands to display the information about these commands displays the prompt again awaiting for the user to enter another command.

2. end Try the current code by compiling and executing it. The user entry is a number of commands with their arguments, if any, separated by pipes, if any. Observe the output of the program to have a better understanding of what is parsed by the parser and how is it stored. Refer to the Notes section to try various types of input. This homework is the second phase in developing a basic shell (Command Line Interpreter). You are required to code the execution of the parsed commands. The user entry is still the same, a number of commands with their arguments, if any, separated by pipes, if any. The output should be the result of the executed commands.
